展成滚刀刃形及切齿齿形的计算

The Calculation for the Edge of General Hob and the profile of Cut Gear

铲磨滚刀齿背的轴截面截形都不一样,本文提出了对直槽零前角滚刀,原始截面刃形在基本蜗杆齿面上,此滚刀计算截面刃形和它所切得齿轮齿形及误差的计算方法.

It is distinct from profile of every axail section of tooth back of relief grin- ded hob.This paper presents a calculating method for the edge of comput- ing section of a hob with straight groove and zero rank angle and for the tooth profile and error of cut gear by it.The original section edge of the said hob is on the surface of basic worm.
